Question

Pls help my with this topic thanks

Answer 1

a) Formula of a cylinder is: V=πr2h

So you simply add in the awnsers already given which

are the height and diameter.

*Remember radius is the half of the diameter. So if 10 is

the diameter, than 5 is the radius.

V= π x 5²x 9

b) Formula of a cone is: π ⅓ r² h

Simply fill in the already given information which are

the height and diameter.
